Abstract: Resumo: A ação da resposta imunológica na infecção de Trypanosoma cruzi envolve dois mecanismos: um que resulta na produçao de anticorpos específicos contra antígenos do parasita e outro correponde a resposta imunológica celular com atividade citotoxica, que mata as celulas infectadas ou aqueles que expressam antígeno parasitario pela acao de linfócitos T citotóxicos. Com o objetivo de abordar o processo de infeccao por Trypanosoma cruzi e o mecanismo de delimitacao no organismo do hospedeiro promovida pelo sistema imunologico, dois modelos matematicos da interacao entre sistema imune e Trypanosoma cruzi são apresentadas. Apesar da simplicidade da dinamica das populacoes isoladas de organismos patogenicos e das celulas, a descriçao da interacao entre eles se torna altamente complexo. Assim, apresentamos o desenvolvimento de dois modelos simplificados pela necessidade de anaílise quantitativa das respostas humoral e celular

Abstract: The action of the immune response in the infection of Trypanosoma cruzi involves two mechanisms: one that results in the production of specific antibodies against antigens of the parasite and the cellular immune response with cytotoxic activity, which kills infected cells or those expressing antigen parasitic by the action of cytotoxic T lymphocytes. Aiming to address the process of infection by Trypanosoma cruzi and the mechanism of delimitation in the organism of the host promoted by immune system, two mathematical models of the interaction between system immune and Trypanosoma cruzi are presented. Despite of the simplicity of the dynamic of the isolated populations of pathogen and the cells, the description of the interaction of them becomes highly complex. Hence, we present the development of two simplified models by the necessity of quantitative analysis of humoral e cell responses
